To all whom it may concern:

Be it known that I, JAMES 1V. NEILL, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful igging Apparatus, of which the following is a specification.

This invention relates to improvements in jigging apparatus, and the main object of the invention is to apply the operating power direct to the paddle, taking all torsional strain ofi'l of the shaft which supports the paddle, and avoiding lost motion and strain on the bearings.

Another' object is to provide a more compact mechanism and save floor space, which would otherwise be taken up by rocker arms and the link.

Referring to the drawings: Figure 1 is a vertical section through the apparatus. Fig. 2 is a section on line x2, Fig. 1. Fig. 3 is a plan view of the casing and the partition.

Heretofore in apparatus of this character the paddle has been carried by a shaft, which extended through the side of the box and was operated by a crank or arm at? tached to the shaft at one side of the paddle, with the result that the shaft is called upon to bear a torsional strain, and the bearings are subjected to a lateral pressure of the shaft, which strains the machine and causes lost motion. 1n the present invention this is avoided.

1 designates the box with a sloping bottom 2. A shaft 3 is extended through the box and is supported by bearings 4 outside the box, as clearly shown in Fig. 2. A suitable packing 5 is provided where the shaft passes through the sides of the box.

Mounted on the shaft 3 is a paddle which comprises a blade 6. which is secured to three arms 7, and 8, the arm 8 being in the center and formed integral with an upper extension 9 forming an operating arm, which extends up through a tubular casing 10 formed as a part of a partition 11, the partition 11 being flanged at 12 and secured by bolts 13 to the sides of the box. A connecting rod 1li is connected to the upper end of the operating arm 9, and is operated in any desired manner by a mechanism not shown to oscillate the paddle 6. The lever 9 is rigidly secured to shaft 3 by set screw 15 and also by key 16 only for the purpose of preventing movement between the shaft and lever in order that the shaft 3 will rock in the bearings 4, as the shaft 3 is passive and only acts to support the paddle and lever 9. All of the operating power is transmitted directly from the lever 9 to the paddle 6, and the shaft 3 is entirely relieved of this strain, being only called upon to support the paddle as a fulcrum. This construction greatly reduces the size of the apparatus, as it removes external connections for operating shaft 3. and thus greatly economizes floor space. A screen 17 is arranged in the box on each side of the partition 11.

What I claim is:

1. 1n combination, a jig tank, a jigging screen therein, a transverse paddle in the tank intermediate the length of the screen and beneath the same, said paddle having bearings at the sides of the tank, a lever extending upwardly from the transversely central portion of the paddle through the jig screen and above the water level. and a sleeve surrounding the lever elongated in the direction of travel of the material and narrow transversely thereof.

2. In combination, a jig tank. a jigging screen therein, a transverse paddle in the tank intermediate the length of the screen and beneath the same, said paddle having bearings at the side of the tank, a lever eX- tending upwardly from the transversely central portion of the paddle through the jig screen and above the water level, and a sleeve surrounding the lever elongated in the direction of travel of the material, narrow transversely and tapering in longitudinal planes.

3. In combination, a jig tank, a jigging screen therein., a transverse paddle 1n the tank intermediate the length of the screen and beneath the same. said paddle having bearings at the sides of the tank, a lever extending upwardly from the transversely central portion of the paddle through the jig screen and above the water level, a transverse overflow partition overlying said my hand at Los Angeles, California, this screen substantially in line with the paddle, 11th day of April, 1914. and a sleeve surroundn0r the lever and connected With said partitin, said sleeve being JAMES W' NEILL' elongated in the direction of travel of the In presence ofmateral and narrow transversely thereof.
